H Ar, L E C.,HEAP,21IlCl GEORGE A. \VooDLEY, c1t1- zensof the United States, residing at Beri gen,'in the county of McHenry and State of North Dakota, have invented, certain new and useful Improvements in Belt-Shifters; and we do declare the following to be a full,

clear, and exact description of the invention, such as will enable others skilled in the art same.

Our invention relates broadly to improvements in belt shifters and more particularly to those designed for use in connection with traction engines.

. It is a well known fact that most forms of traction engines are equipped with gearing adjacent the inner side of the'fiy wheeland that a belt passing around said wheel often slips therefrom and becomes entangled in the gearing thus causing unnecessary mutilation of the belt.

- It is to prevent such an occurrence, that we have provided the extremely simple construction herein described and claimed and shown in the drawings wherein Figure 1 is a side elevation of a portion of a traction engine equipped with-our invention; Fig. 2is a top plan view thereof;

Fig. 3 is a vertical transverse section as seen on the line 33 of Fig. 1. Fig. 4 1s a perspective view of the lever.

In the accompanying drawings, we have shown a portion of a traction engineiE which is equipped with the usual fly wheel W and gearing Gwhereby power may be Passing around the fly wheel W and leadi 'ing forwardly therefrom is the usual belt B which is designed forthe running ofother V V provided an upright rollerll which is rev-j transmitted to itsdrive wheels (not shown).

V H .In order to retain the belt B properly in its position upon "the wheelW', we have olubly" mounted upon an upright bolt 2, said bolt passing through the two arms 3 of a forked lever 4 theshank5 of said lever as well as the arms3 thereofbeing formed BELT-SHIFTER.

Located above and below the intermediate portions of the arms 3, are upper and lower attaching brackets 7 and 7 said brackets having their inner ends curved respectively upwardly and downwardly as seen at 8 and 8, this being done to facilitate the attachment of said bracket to the boiler of the engine E, while their outer ends are bent as seen at 9 and 9, to cause the same to hem horizontal planes in contact with the arms 3, an upright pivot bolt 10 being passed through. said arms and throughthe portions 9.

The device, as above described, is positioned in advance of the fly wheel WV with itsroller 1 contacting with the inner edge of the belt B, thereby preventing said belt from moving inwardly. It will be noted that when the parts stand in this position,

the arms 3 lie substantially parallel with the belt B and that due to the formation of said arms, the same being curved throughout their lengths, the shank 5 is spaced in- We are aware that numerous other forms wardly from saidbelt. Pivotally connected v of belt shifters have been employed for the purpose of shifting the belt from one position to another but are not aware that a shifter of the specific formation herein described and claimed has been employed. This specific type operates to great advantage in spite of its simplicity. Particular emphasis is laid upon the fact that the bend of the upper arm 3 serves not only to space said arm above the shank 5 the necessary amount, but acts as a stop for contact with the operating rod 11 when the device is moved to inop erative position. reach dead center and will be readily operable at all times.
